FEEDER FOR GRAIN-BEARING STRAW.

To all whom Lt may concern:

Be it known that I, SAMUEL BERT Mo- CoMB, a citizen of the UnitedStates, and resident of, Zenith, in the county of Stafford and State ofKansas, have invented a certain new and useful Feeder for Grain-Bean ingStraw, of which the following is a full, clear, and exact description.

The principal objects which the present invention has in view are: toprovide a mechanism for extracting wheat or other grain from a stack anddelivering it to a threshing machine; to provide a mechanism fordelivering the wheat from a stack to a threshing` machine, which may beoperated on either side of the said threshing machine; and to provide aconstruction for accomplishing the above-mentioned objects, which islight, durable and simple.

One embodiment of the present invention is disclosed in the structureillustrated in the -accompanying drawings, wherein like characters ofreference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a machine constructed in accordance withmy invention, shown in its application to a threshing machine; Fig. 2 isa plan view of the boom of this machine, said view being broken intosegments and contracted lengthwise; Fig. 3 is a detail view, enlarged,showing a hoisting sheave and a trip for throwing the clutch foroperating the hoisting drums out of engagement therewith; Fig. 4 is adetail view of the lifting fork; Fig. 4a is a side view of the liftingfork showing the parts thereof disposed in their holding position; Fig.4b is a similar view illustrating the parts of the lifting fork in anextended or emptying position. Fig. 5 is an enlarged detail view partlyin section, of the mounting for the boom, and the driving shaft, takenon the line 5-5 in Fig. 2; and Fig. 6 is an enlarged detail sectionalview of the clutch and clutch yoke, taken on the line 6-6 in Fig. 2.

The present invention more particularly has in view the provision ofhoisting devices to replace manual labor. There is here employed amechanism which engages the material to be handled by pressing upon thesame, the pressure being released at the delivery station of the liftingmembers. These members consist in the construction illustrated moreparticularly in Fig. 4 of the drawings, and comprise a fork body 7,through a central perforation in which is Specification of LettersPatent.

extended a lifting rod 8, which at the lower end, is pivot-allyconnected to toggle arms 9, which at their outer ends are pivotallyconnected to rods 10, threaded through perforations formed in ears 11set out from the ends of the fork body 7.

In Fig. 4 is shown the normal position of the tines 12 of the liftingmember or fork. The ends of the rods 10, 10, are fixedly mounted in theends of a flexible bail 13, constructed from spring material, andprovided with a curved middle section 14 to induce the spreading actionto transpire at this point, In its action the lifting fork is operatedby the central tines 12a being lat erally extended by the spread of thetoggle arms 9. This is caused by the pull on the cable 15 and rod 3. Inthis position the tines 12fL are moved outwardly toward the tines 12,imprisoning any straw which at the time of the spread is held betweenthem. Then the fork is raised to the upper end of its travel, the bail13 contacts with the finger 41 and is thereby depressed, spreading thelower ends of the said bail. The bail is connected with the outer tines12 and when said bail is spread the tines 12 are removed outwardly fromthe tines 12a, as shown at Fig. 4b, thereby releasing any supported orcarried straw.

To the rod S is connected a lifting cable 15, which is extended over asheave 16 fixedly mounted on a boom 17. From the sheave 16 the cable 15is threaded backward along the boom around the guide sheaves 18, 18, toone of the drums 19, 20, 21 and 22. The said drums are loosely mountedupon a driving shaft 23 on which a suitable driven pulley 24 is mounted.The pulley 24 is adapted to receive axdriving belt connected with thedriving Jmechanism of the thresher upon which this mechanism is mounted.The drums 19, 20, 21 and 22 are thrown into operative engagement withthe driving shaft 23, by the clutches 25, 26, 27 and 28. These clutchesare of the usual cone-friction type, having suitable annular clutches,wherein pins or antifriction devices are extended from a surroundingring or yoke. In the present instance the said pins are mounted in therings 29, fixedly secured on levers 30, 30, which are pivotally mountedin cross framing members 31 at 32. At the other end of the levers,secured thereto by the links 33 are the levers 34, which are manuallyoperated to throw the clutches 25, 26, 27 and 28 into engagement-- withtheir respective drums.

The levers 30 are provided with an extension at the side of the pivots32 opposite that upon which the rings 29 are mounted. To thesekextensions are connected various cables 35, 36, 37 and 38, which areguidably mounted upon suitable sheaves, and connected at the far endwith trips 39. The trips 39 are illustrated more particularly in Figs. 2and 3 of the drawings, they being pivoted at 40 upon the boom 17 andnormally held in a substantially vertical position. Their lower ends arebifurcated to form fingers 41 which straddle the hoisting cable 15 insuch manner that when the fork is raised, carrying the load, the bail 13strikes upon ythe fingers 41, causing the trip 39 to rock in such manneras to throw the free arm 42 to draw upon the cables 35, 36, 37 or 38.The effect of this pull upon the trips is to cause the levers 30 toremove the clutches from engagement with the winding drums, therebyarresting the pull upon the hoisting cables 15.

When the bail 13 of the fork, shown in Fig. 4 of the drawings, israised, after having been provided with its load, by the hoisting cable15, it is moved upward until the bail 13 strikes under the fingers 41,producing the action above described to arrest the pull upon the cable15. Before the cable 15 is fully arrested, however, the pull of the saidcable uponthe rod 8 and the arms 9, 9 connected therewith, raises thesaid rod 8 and spreads the arms 9, 9 and the tines 12, 12 connectedtherewith, causing the said tines to release the straw held between thesame. By the same action the spring bail 13 is flattened and extended,drawing outward the tines 12, 12 with which the ends of the bail areconnected. This separation of the various tines 12, 12 releases the loadcarried by the ksaid forks and permits the same to drop upon the draperor conveyer belt 43.

While I have herein described the fork illustrated in Fig. 4 of thedrawings, I do not wish to be understood as confining myself to theemployment of such a device. Any of the well known trip operated forksmay be used in connection with 'the trip 39 and the transmissionmechanism connected therewith.

When this action transpires, it will be found that the forks aredisposed over a draper or conveyer belt 43 which is operated to advancethe material when thus deposited upon its upper surface, to theseparating Iand feeding device with which this machine or the thresheris provided.

In the present instance, I have shown la rigging for four liftingmembers or forks. It 'will be understood, however, that I am not limitedVto this number, but may increase the same at will.

The boom 17 is constructed in the lightest possible manner commensuratewith strength. The construction employed by me, preferably, is thatshown in Fig. 1 of the drawings, wherein a bridge truss method ofconstruction is employed. The boom 17 is extended laterally, and issupported by a tie rod 44 secured to the upper end of a mast 45, the tierod being provided with a swivel 46 whereby the said rod is tightened.At the inner end, or the end adjacent to the mast 45, the angle ironsfrom which the boom is constructed, are bent downward, and are securelymounted upon the frame of a large 'bevel cog wheel 47, provided with asuitable bearing within a base frame 48; as shown in the presentdrawings, the mast 45 constitutes the pivot for the said wheel, and isstepped in a socket 49 in said base frame 48. Suitably pivoted in thebase frame is an inclined shaft 50, upon which is mounted a pinion 51held in toothed engagement with the large bevel cog wheel 47. The shaft50 is `provided with a crank handle 52, by means of which and of thepinion 51, the boom 17 is moved circularly from side to side of thevehicle upon which it is mounted. y

The driving mechanism connected with and operated by the driving shaft23, is suspended upon the framework of the boom by brackets 53, theouter ends of which are connected by a framing member 54, upon which arepivoted vthe levers 34, 34. The mast is supported against the pull Aonthe rod 44 by yguys 55, 55, connected to the top of the mast and to theframing member 54.

The. arrangement of the guys is illustrated Y best in Figs. 1 and 2 ofthe drawings.

The conveyer 43, shown, is the draper of the usual threshing machine. Atthe lupper end thereof are distributing wheels 56 and 57, each providedwith propelling extensions, adapted to deliver the grain bearing strawfrom the conveyer 43 into the hopper of the threshing machine. In thepresent arrangement, I prefer to drive the wheel '56 at a `much higherrate than the wheel '57, causing the wheels to separate the massed ormatted straw as it is delivered to the threshing machine.

The outerend fof the boom 17 is steadied by suitable guys 58 and 59. Thelatter 1s shown with a suitable device `60 of any suitable constructionfor winding up the slack of the guy 59. In operating the present machinewhere there is considerable side thrust, due to the extension ofthe boom17, I prefer to lift-'the end of the thresher from `the ground by meansofjacks v61, which are of the ordinary construction andare adapted tolift the end of the vehicle by means of a cross rod 62, which issufficiently heavy to carry the weight of the vehicle.

With an apparatus constructed as herein disclosed, and as shown in theaccompanyino' drawings, the operation of pitchinglwheat or other grain,is as follows: The thresher is placed in position between the stacks orricks of the grain bearing straw. The boom 17 is extended over one ofthe ricks by adjusting the same by the crank 52 and the gears 51 and 47.Having placed the end of the boom in proper position, it is held thereby driving the stake of the guy rope 58 into the ground, and byanchoring the device 60 on the opposite side of the extended line of theboom, and then taking up the slack in the guy 59; the boom is thus heldreasonably firm. The winding drums 19, 20, 21 and 22 are released topermit the various forks 7 to descend to the ground. Here the tines 12,12, are inserted into the grain bearing straw, and so held until theforks are lifted by the cable 15. The cable 15 pulling against thetoggles 9, 9, extends the inner tines 12, 12, against the outer tinesholding the straw between them. The operator on the deck of the thresherhaving thrown the lever 34 to engage the clutches 25, 26, 27 and 28 withtheir respective drums, the remainder of the operation is automatic. Thecable 15 draws the fork upward, until the bail thereof strikes upon thefingers 41 of the trip 39, which releases the clutch for the particularwinding drum drawing the particular fork. By the same action which tripsthe said clutch the load carried by the fork, is dumped on the conveyer43 as above described. The clutch having been released, the weight ofthe fork immediately returns the fork to the ground, in position torengage the straw, and where an operator inserts the tines within thestack or rick to again initiate the operation above described. 1t willbe seen by the drawings, and from the above description, that, as shownin the` present instance, there are four forks, operv ating to depositloads on different points of the conveyer 43. When, now, the strawA hasbeen transferred from the stack or ground within the radius of operationof the boom, as formerly placed, the guys 58 and 59 are slackened, andthe boom 17 is swung to a desired position, where it is again secured bythe guys 58 and 59 as above described. The operation again is pursued asdescribed. In this new position, however, it will be necessary toprovide a conveyer for the threshing machine which will accommodate thethrow of the boom 17. To tighten the guys 58 they are carried back overthe boom 17 and wound upon the drums (30a- 60au which are mounted upon ashaft 61'n1 on the upper framing of the boom 17. The shaft 61a ispropelled by the handle 62, and is held against return by a pawl 63,which engages a ratchet 64. After the anchors for the guy rods 58 havebeen placed,

the drums (SOL-60"l are wound to take up the slack of the said guy rods.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
